Dual USART, Second USART sends but not receives, PIC18F24K22

My application is utilizing both USARTs for this chip. The primary USART is working fine. The second USART will transmit but will not receive. I sususpect I have an issue with the configuration. I did see this note for the RX2 pin in the documentation with Note 2 below for the RX2 pin. I do not know what this information means.

also, char2 we cant see how it was declared but if its a byte then it can only receive a single hex digit
it may never be $13 it may only be 0 to F
$13 sent as serial hex is ascii 0x31,0x33 ie two chrs

It is now working. It was the issue of sending bytes and data mismatch. I had HSERIN2 100, main, [HEX char2] with char2 defined as a byte. When I dropped the HEX modifier, it worked properly and that is my last issue to resolve. My project is not complete and thank you everyone for your input.
